Conquest of Space

This is a story of tomorrow, or the day after tomorrow, when men have built a station in space, constructed in the form of a great wheel, and set a thousand miles out from the Earth, fixed by gravity, and turning about the world every two hours, serving a double purpose: an observation post in the heavens, and a place where a spaceship can be assembled, and then launched to explore other planets, and the vast universe itself, in the last and greatest adventure of mankind, the plunge toward the... conquest of space!
